3.9-rc1: crash kernel panic - not syncing: Can not allocate SWIOTLB buffer earlier and can't now provide you with the DMA bounce buffer

CC'ing kexec ML. Also mentioned that 3.8 has no such issue.

This message looks suspicious and out of range while 3.8 reservation
looks within the range.

[    0.000000] Reserving 128MB of memory at 5216MB for crashkernel
(System RAM: 3977MB)

Wondering if anything to do with memblock again...
